"The Protector" was a very discreet palm pistol developed in the late 1800s by a French inventor, produced in bulk by the Ames Sword Company, and sold by the Chicago Firearms Company. They are mechanically double-action turret revolvers with a unique grip design meant to be to be fired by squeezing. The first few were made in France by the original inventor, and later licensed to an Irish-American who sold them through first the Minneapolis Firearms Company and later the Chicago Firearms Company. Most are in an extra-short .32 caliber rimfire cartridge, but a few were also made in both .41 and .22 calibers.
